The Frederick Douglass School educated African American students in Seaford from 1922 to 1966, with Professor Robert W. Thomas Sr. serving as its only principal during that time. Built as part of philanthropist Pierre S. du Pont's school rebuilding program, it initially taught grades 1 through 11. Renovations in 1956 expanded the school to 18 classrooms, with administrative offices, a cafeteria, gym, auditorium, home economics room, industrial shop, music room, and library. When a new Seaford High School opened in 1966 and the district restructured, the building was desegregated and became the Frederick Douglass Elementary School.
